６０−５１８５７公報に記載の先行技術がある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fan-shaped spray nozzle, and in particular to a nozzle suitable for finishing coating that improves atomization and suppresses the generation of tails. [Technology] Various types of fan-shaped spray nozzles for painting that prevent the occurrence of tails have been announced, and one example is the prior art described in Japanese Patent Publication No. 60-51857.

いた。In this prior art, a lip-shaped orice-shaped nozzle is generally formed by a concave hole consisting of a dome-shaped concave surface and a cylindrical flow path and a V-shaped groove intersecting the concave hole, and the concave surface and the cylindrical flow path A corner part is formed at the boundary with the cylindrical flow path, the depth of the V-shaped groove is selected so as to intersect with the corner part at a specific ratio, and furthermore, the inflow liquid is formed upstream of the cylindrical flow path. This prior art is characterized by providing side inflow channels that collide with each other, and in this prior art, when forming the corner, the size of the corner itself is appropriately selected, and the corner is formed with side heat. In addition, the troughs of the V-shaped grooves must be sharp, and the intersecting dimensions with the corners must be strictly observed.
This type of nozzle is very difficult to manufacture, and tails are likely to occur when the upstream side inflow passage is omitted.Therefore, there has been a strong desire for a nozzle of this type that is simple in structure and easy to manufacture.

巻き込まれる状態のもとに消滅することが判る。In addition, in a fan-shaped spray nozzle having a lip-shaped nozzle formed by the intersection of a dome-shaped recessed hole and a V-shaped groove, a tail generally occurs under the following tendency. , if the depth of the figure-7 groove is appropriate and the corner is too large or there is no corner, spray patterns as shown in Figures 1 and 2 will appear, and the corner will be too small. When the V-shaped groove is properly shallow and deep, spray patterns as shown in Figures 3 and 4 appear, respectively.From these spray patterns and the formation of the tail, it is possible to When provided, the pattern generating element is separated into two parts, one of which is directed outward away from the edge of the main spray, and the other of which is directed to the tip of the edge of the main spray or inward of the main spray. If both the corners and the V-shaped grooves are correct, it is assumed that significantly fewer tail-generating elements will appear in the form of a fork, and fewer outwardly directed tail-generating elements will actually be visible. It can be seen that although it has a striped shape at the base end, it scatters shortly after being ejected and disappears as it is caught up in the main spray before reaching the surface to be coated.

ることを目的とするものである。It is thought that it is possible to flatten and atomize by eliminating bifurcation caused by liquid flow collision from both corners in the trough of the V-shaped groove, and to reduce the flow resistance of the cylindrical flow path, and By creating turbulent flow and a small turbulent flow just upstream of the lip-shaped nozzle, it is possible to prevent the generation of tails and improve atomization at the same time. Therefore, the present invention can be easily manufactured. In addition, it is an object of the present invention to provide a fan-shaped spray nozzle that can easily and reliably prevent the occurrence of tails.

のである。In order to achieve the above object, the present invention not only increases the flow cross-sectional area upstream of the dome-shaped concave surface where the lip-shaped orifice-type nozzle is formed, but also increases the flow cross-sectional area of the flow path in the front end portion that contacts the rear end of the dome-shaped concave surface. In the direction of the V-shaped groove, a straight guiding part is formed without a stepped part, and in the direction perpendicular to the V-shaped groove, a shoulder-shaped stepped part is formed, and the V-shaped groove intersects this with the stepped part. It is characterized by being formed in a state where it does not.

ることができるのである。In the embodiments shown in FIGS. 5 to 7, a nozzle main body 1 made of a super hard material such as cemented carbide or ceramic is provided with a dome-shaped concave surface 2 and a rear end section of the concave surface 2 upstream of the concave surface 2. A tapered cylindrical flow path 3 having a flow cross-sectional area significantly larger than the area is provided in a rear open state, and the front end of this cylindrical flow path 3 has the dome-shaped concave surface with an oval or oval cross section. 2 has a straight guiding part 4 formed by smoothly continuing the short diameter part, a shoulder-shaped stepped part 5 in the long diameter part, and a 7 in the front end of the nozzle main body 1.
The dome-shaped concave surface 2 and the figure-7 groove 6 are formed by carving the groove 6 at a depth such that the valley does not intersect with the step 5 while keeping the groove 6 aligned with the short diameter direction of the cylindrical channel 3. A lip-shaped injection lower is formed by the intersection of the two, so that the pressurized liquid such as paint supplied from the back is staged immediately before being ejected from the injection lower without pressure loss in the cylindrical flow path 3. The part 5 disturbs the flow and generates turbulent flow and small vortices to help promote atomization and prevent the generation of a tail. In particular, at both ends of the lip-shaped jet lower, there are step parts in opposing states that gradually decrease from both sides. 5, and coincides with the straight guiding part 4 of the flow path 3, so that the flows deflected by the gradually decreasing step part 5 and colliding with each other are not bifurcated, and the straight guiding part 4, it is possible to eject a fan-shaped spray from the injection lower while colliding with the straight-advancing flow while reliably preventing the generation of a tail.

ことができるのである。The dome-shaped concave surface 2. Cylindrical channel 3. The step portion 5 of the linear guide portion 41 may be formed in the powder molding process before sintering. That is, as illustrated in FIG. At the same time, a dome 10 is formed at the distal end of the cylindrical body 8, and a dome 10 is smoothly continued on both sides of the proximal end so that a step is not formed at the connecting part of the cut part 9. By adopting the protruding core 11 in this manner, molding can be easily performed.

端寄シ部に僅かに及ぶように延長状態に形成してもよく

べく尖鋭に形成することが重要である。The shoulder-shaped step portion 5 may be formed not at right angles to the nozzle axis but slightly obliquely as shown in FIG. 10, but it is preferable not to give roundness to the vicinity of the tip of the tapering portion of the step portion 5. It is desirable and important to form the valleys of the 7-shaped grooves 6 as sharply as possible.
以上説明したように本発明においては、次のような効果

図ることができる。(b) Since the formation of the fan-shaped step part inevitably makes the cylindrical flow path for liquid supply large in diameter, the flow resistance in the cylindrical flow path is reduced, pressure loss is suppressed, and the mist is reduced. It is possible to promote the development of

生が認められなかったのである。(c) Since the stepped portion is formed close to the valley of the V-shaped groove and gradually decreases from both sides, and the V-shaped groove is provided to such an extent that it does not intersect with the stepped portion, disturbance is caused by the stepped portions on both sides at both ends of the lip-shaped nozzle. The deflected flow accompanied by the jet collides head-on with the forward flow generated by the straight guiding section at the same time, so that the ejected flow from both base ends of the nozzle is not bifurcated or striated, but is continuously added to the main spray. According to the results of implementation, the major axis of the shoulder-shaped step is twice the diameter of the dome-shaped concave surface based on the shapes shown in Figures 5 to 7. If the depth of the V-shaped groove is made to be approximately the same as the surface of the stepped part, the nozzle described in Japanese Patent Publication No. 60-5.1857 will have a structure that lacks the side inflow channel. In comparison, a remarkable effect is recognized, and when using melamine resin paint with conventional products, 701 = p
However, with the nozzle of the present invention, the pressure of the same paint is significantly lower than 30 to 9.
When sprayed under the same conditions as ~~, no tail formation was observed.
（ｄ） Ｖ字状溝の深さについて、段部と交叉するよ
うに深く形成しない限シ、深さの許容範囲が広く製作上
著しく有利である。(d) As long as the V-shaped groove is not formed so deep that it intersects with the stepped portion, the permissible range of depth is wide, which is extremely advantageous in manufacturing.
（ｅ） 形状が比較的簡単であり、従って成型により
溝研削前の素材を容易に製作することができる利点があ
る。(e) The shape is relatively simple, so there is an advantage that the material before groove grinding can be easily manufactured by molding.
